We look at the division of 496921 by 30 
We want to divide 496921 by 30.

Advancing to step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 30

Going ahead to step 2:
When dividing 49 by 30, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 49 and we're left with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 30

On to step 3:
196 divided by 30 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 180 from 196 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 30

Going ahead to step 4:
30 can be fit into 169 5 times, resulting in a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 150 from 169 to get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 30

Advancing to step 5:
192 divided by 30 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1656.0
If we subtract 180 from 192, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 30

Going ahead to step 6:
If we divide 121 by 30, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 16564.0
Subtract 120 from 121 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 16564.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 16564.03
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 16564.033
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 16564.033 with a remainder of 0.001.
